How can I go about finding this out?

How can I go about finding out whether or not the giving-up-of-my-child for adoption has been finalized? I never went to court; never saw a judge and lawyers were never involved. Only thing that I did was sign papers relinquishing my rights. I went to the courthouse to get them notarized. Only paper the court would not notarize was of one that required the fathers' signature; however told me that if I could find a notary to do so, that it would be fine. I had a friend who was a notary who did this for me; but not in the presence of a judge/courtroom/any other legal witness; just my home. I never received or heard of any verification that the adoption went through. The people who have my son will not cooperate with me. It's been almost a year. If the adoption hasn't been finalized, do I still have the right to change my mind and keep my son? If anyone has any vital information on this for the state of Georgia laws, please provide resources.
